摘要

Seventeen lines of upland paddy were evaluated for estimating genetic parameters, correlation coefficient and reaction against brown spot disease. The lines exhibited considerable variation for seven traits out of nine characters studied. Mean yield/plant was highest in Bhalum-3 (29.26 g) followed by RCPL-412 (28.46 g) and Bhalum-2 (28.06 g). Entries RCPL-412 and RCPL-413 exhibited highest number of grains/panicle (188.0 and 165.44, respectively). Narrow differences were observed between PCV and GCV for majority of the traits. Yield per plant was significantly correlated with number of productive tillers per plant (0.4280), number of grains per panicle (0.4085) and negatively correlated with days to 75% maturity (-0.5949). Lines Bhalum 1, 2, 3, 4 and RCPL 412 and 413 showed resistant reaction against brown spot disease of rice.
